Sorry I'm late to the party, but I think something here is overlooked.
People can be jerks in the results thread, I agree with that. We get the humblebrag, the ego stroking, the "omg I'm gonna fail [oh oops got 90]" and so forth.
But as much as that's the case, I fail to see any appreciable harm caused to users. AN has some incredibly intelligent people. But it is not a bubble. I would give our users a bit more respect than to assume that they are unaware how uni (or VCE) marks are actually distributed. That 75 is a great score, for example. And that they shouldn't be upset because some people on the internet got 90s. Beyond conjuncture, I don't think there is any evidence that the threads have caused any harm.
I don't like some of the behaviour on those threads myself, but I don't think the mod team should step in to exclude them based on a some people's conduct, when it is not harming anyone. Ultimately, it comes back to those who engage in it who are the ones who come off as unpleasant. Not the mod team's job to regulate that.
I also don't understand the distinction made between results thread and signatures. I don't see how Specialist [50] Methods [50] English Language [50] Chemistry [50] Physics [50] Biology [50] ATAR: 99.95 is any less 'daunting' than the uni (or school) threads.
And the reason why I'm for the retention of the threads is that, as is apparent by their wide (and appropriate) usage, there's demand for them. It's a fairly laissez affaire approach, but I think it's the best one.
